a blade; a blade for such a razor in .the form of a thin flat,n0n-flexible member; means for engaging the blade and its supportingmember consisting of one. or more tongues and cooperating openings, thetongues'beingon the blade and the openings on the other member; and ingeneral the making of a safety razor reduced to its simplest form in allrespects.

The construction hereinafter set forth permits the blade support and itshandle to be developed from one piece of stamped sheet metal, therebyeliminating the necessity of any forging, machining, or otherexpensiveoperations thereon, and so greatly reducing the cost of manufacture. Theconstruction also provides a safety razor, the blade of which may bemade in a standardized form and interchangeably used withdift'erentforms of supports. These and other objects which will be apparent to.those familiar with the art will more fully ,appear in the followingspecification.

-Referring to the drawings, Fig; 1 shows ahoe-shaped blade supportforming one of the two essential parts-of the complete razor constructedaccording tothis invention, the view being an elevation of the handle,standing on end; Fig. 2 isaview similar to Fig. 1 but taken at rightangles thereto and with the razor blade in position on the handle; Fig.3 shows another formof holder apd handle the two portions being in alient; Fig.4 is a section on the line IV- V of Fig. 3; Fig. 5 is;apersp'ec- 'tiv'e view of a referred formof blade, suitable for' use withany of the supports illustrated; Fig.- 6 shows aspecial blade holderapplied to the ordinary formof razor handle; Fig. 7 is an enlargedpartial section through the blade and its support,;the blade having beenapplied to the support, ,fbut not having been moved longitudinally intoper nanent engagement therewith; and Fig. 8

is a :section through the blade and its support showing the relativeposition after the f blade has been longitudinally moved intofengpgemen't with the support. The lasttwo figures also show amodification in the end of the blade. H Safetyrazors have been madeheretofore,

in which ablade of substantial thickness having a pair of slots, eachslot having a.

countersunk ledge adjacent thereto, has been combined with a support,the support having a shank pivoted thereto and being provided with anintegral guard having a pair of integral lpgs off-set from said guardand adapted to passthrough the slots and enfiexiblewafer steel bladeshave been provided for attachment to a support by means of proJectingoverhanging lugs on the support adapted to extend through holes in theblade, and to engage the blade, holding it means of the resiliency ofthey blade itself,

Qgage the ledges of-the blade, to hold the I blade and guard together..Likewise thin "in a curved position against the handle by and withoutany additional locking member. V The present invention is distinguishedfrom each of these by the fact, among others,

that it does not use a wafer blade, and the blade itself is of uniformthickness through-. out its body and is not bent or distorted in any wayeither while held in operative posi tion or in order to place'it inoperative position. Furthermore the blade of the present device is notheld in position by a third part, clamping theblade between s uchthird vpart and the handle as has heretofore been} the practice wherever astifi' blade was used.

' The present invention in all of. its forms provides for holdingthe'blade andits'sup port togetherby means of one or more ofiset tonguesformed integrally with the blade,

which tongues engage the. holder andby their resiliency hold the t.seburely to: getherunder pressure. f

the ace of. the ordinary fashioned razor handle; It .e'

is shown a meta member, v11',adaptedtoitaQke bladeinjtlie old" byrolling up a strip of sheet metal to form a suitable hand-hold at oneend, the other end being fashioned into a supporting plate S adapted tohold the blade as below described. For example in Fig. 1 the same pieceof metal sheet which forms the handle H forms the blade support S. Theouter edgeof the supporting portion S has a series of openings 0therein, which are separated by small grill-like portions of metal Gforming a guard portion which readily slides over the face of a personshaving, and permits the blade B, shown in Fig. 2

to come in contact with the beard. The por- I S has cut through it twosets of openings C and C. a In the form shown in Fig. 3 the sheet metalthat forms the handle H likewise .forms a blade holding portion S and ateach edge of this flat portion the metal is cut away to form a series ofopenings 0 with intervening guard portions of metal G The outer edge isturned sharply inward, forming a terminal flange F The section shown inFig. 4 clearly shows the construction just above referred to. Thesupporting portion S has a pair of openings C intermediate which thereis a small rounded hump F The form of handle shown in Fig. 6 comprisesthe metal bar 1, which is pivotally attached to an ordinary razor handle2 by a rivet 7. This rivet passes through the forked end of the handle2, the slot 8 forming this forked portion being extended far enough intothe handle so that the tang 9 of the member l'can pass through theslot,-

thus permitting the razor to be used for shaving, with either hand orwith either edge of the blade. as will be obvious.

-This member 1 likewise has a flattened blade supporting portion Ssimilar to portions Sand S above described, and this flat portion has apair of openings C there.- through, with an intermediate raised hump P,as illustrated. The edges of the supporting member S are serrated,forming guard teethG and these serrations are similar on each side ofthe member, as illustrated.

The preferred form of blade is shown in Fig. 5. llt consists of a pieceof thin flat steel B having two cutting edges E, and two raised integraltongues T, which are struck up from the body of theblade 1B and havingre-entrant bends 10, and outwardly turned terminal portions 11, as moreclearly foration 13.

This bladeis adapted to be used with each of the three. forms of holdersillustrated respectively in Figs. 1 and 2, Fig. 3, and Fig. 6.

The blade B is fastened to its support by laying it flat upon thesupporting surface S, the tongues T being positioned in the openings C,and occupying the position shown in Fig. 7. It will be observed that theraised hump P, when the blade is laid upon the fiat supporting surfaceS, lies in the elongated opening 13 of the blade. With the blade in thisposition, it is pushed longitudinally on its supporting surface. Theterminals 11 of the tongues T pass outside of the undersurface of thesupporting plate S, and further movement causes them to ride upon theunderside of said supporting member and to engage that member, as shownin Fig. 8. The movement to this position necessitates a springingoutward of the tongues T, and consequently results in a resilientlocking action of such tongues upon the supporting member S. At the sametime, the middle portion of the blade rides up over the hump until thatmember registers with the round opening 12 in the blade, as illustratedin Fig. 8, which acts as a lock for holding the blade firmly in placeupon its support. This hump P and cooperating hole 12 are not absolutelynecessary, since the blade will ordinarily be held with suficientcertainty by the resilient force of the tongues T.

llt will be observed that the blade illustrated in Fig. 5 may beinterchangeably used with any of the forms of support and the difi'erenthandles shown. With the supports shown in Figs. 3 and 6 the blade isheld in position so that either side may be used for shaving withoutchange. With the support of Figs. 1 and 2 however only one cutting edgeis in position for use, and in orlltlll der to use the other edge, theblade is taken 0d, turned end for end, and then engages the other pairof holes C or C, as the case may be, of the support shown in Fig. 1.

The blade may be provided with a downturned flange 15, at one end whichmakes it easier to slide it into place by pressure with the fingers Thisconstruction is shown in Figs. 7 and 8.

It will be apparent that many modifica tions may be made in varying theattaching elements. No attempt has been made to illustrate all of them.Instead of holes, loops of metal may be used to engage the tongues, andother equivalents. These are understood to be within the scope of theappended cl.
